This is the video which explains about the ways to use ‘HEX KEYS’ properly. Those people who are in the actual engineering and robotics class or clubs that are related with vex robotics must know. In the video there are several hex keys listed : shorter(thicker) one is 6/64 and the longer(narrow) one is 3/32. Try to use those small hex keys to use collars because they can be easily damaged. Do not tighten up to the very end or you will ruin the screw’s head permanently.
